为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，包括但不限于对多个实施例的组合，都属于本公开保护的范围。
本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
随着移动互联网技术的不断发展，人们的日常生活已经高度信息化，而直播技术解决了人们在不同地理空间上异地接收直播地信息的一种高效手段。近年来兴起的网络直播，更是给人们的娱乐生活增加了很多乐趣，收到了人们的追捧。大量主播纷纷加入了网络直播的行列。而通过移动设备来进行直播，以其简便性受到了很多主播的青睐。但是，随着观众对于直播质量要求的不断提高，主播在进行直播的时候，需要进行音频合成，如添加“入场音”、“暖场笑声”、“鼓掌声”等等音频效果到直播应用中。
面对这种需求，对于大多数主播来说，只能够通过购置一套专业的直播设备，包括：台式电脑、专业声卡、若干个中间转换器/衔接器等专业直播辅助设备来实现直播中的音频合成需求。
图1为本公开实施例提供的现有室内主播使用的直播设备套件结构示意图。如图1所示，直播设备套件包括：移动终端101、中间衔接器102、中间转换器103、声卡104、台式电脑105。
其中，移动终端101中安装有直播应用。
中间衔接器102用于解决移动终端101在长时间直播时，充电接口被数据线占用而无法充电的问题。
中间转换器103用于将台式电脑105中的特效数据转接到移动终端101中，并且连接耳机后可以给客户提供耳返功能，还能够解决声卡104只能单路输出而不能反向接收直播应用输出的音频数据的问题。
声卡104与麦克风连接，实现音频模拟信号转换为数字信号，输入台式电脑105中进行各种音效处理。
但是，图1所示的方式不但造成直播成本的提高，需要配置多个辅助设备，而绝大多数主播不具备专业技术，无法自己去配置这一套设备，因此还需要配备专门的技术人员团队来构建、运营和维护这套专业直播设备，这些都使得本已通过手机等移动终端降低了的直播门槛，又被提高了起来。
并且，由于连接了多个设备，使得整套直播设备的稳定性容易受到各种因素的影响，任何一个设备的接插件插口出现问题，或者线路由于某种原因断路，都会使得系统无法工作。
基于上述技术问题，本申请的发明构思旨在：
通过一个直播终端直接让主播在直播的时候通过屏幕或者按键快速合成所需要的音频到直播的音频流中。使得直播无需多个设备，仅用一个小型设备就能完成音频合成，也无需专业技术人员团队参与运维，主播一人即可在直播时实时添加合成音频。
下面结合附图对本申请提供的音频合成方法进行详细介绍。
参考图2，图2为本公开实施例提供的音频合成方法的流程示意图一。本实施例的方法应用在直播一体式终端中，该音频合成方法包括：

其中，综合透明度是利用预设模型，根据音频合成控件中各个显示元素的透明度来确定的。具体的，某个控件上各个显示元素的透明度先乘以其对应的预设权重值，然后将各个乘积相加即为综合权重值。
例如：一个按钮控件，其背景色的透明度与按钮控件上的文本的透明度分别乘以对应的权重值，再求两者的和，即为按钮控件的综合透明度。
在一种可能的设计中，所述显示屏包括：触控屏和非触控屏。

RFID标签钥匙只要靠近触控屏所对应的预设感应区域，则安装在直播一体式终端上的读卡器或读卡电路，识别RFID标签中包含的待合成音频信息，即接收到了音频合成操作。
S203：在安装了直播应用的直播设备中，将待合成音频与初始音频进行合成，并将合成后的目标音频作为直播应用的输入音频。
在本步骤中，待合成音频为音频合成操作所指示的音频，初始音频为直播设备通过音频采集设备接收到主播所发出的，和/或，直播环境中的声音信号。
直播应用将目标音频编码后，通过网络传输给直播平台服务器，再由直播平台服务发送给各个观众。
需要说明的是，待合成音频包括：笑声、出场/入场声、鸟叫声(如乌鸦叫声)、掌声、打耳光声、枪声等等。

在上述三个实施例的基础上，本公开提供的音频合成方法还能够在直播前，在直播一体式终端上，通过专门的声音设置界面对合成控件的显示状态以及各项声音控制参数，下面以具体实施例来对具体步骤进行说明介绍。
图7为本公开实施例提供的音频合成方法的流程示意图四。本实施例的方法应用在直播一体式终端中，该音频合成方法包括：
S701：在没有开启摄像头或者直播开启之前，获取用户的声音设置操作。
在本步骤中，直播一体式终端检测到用户点击声音设置按钮，或者是通过预设的直播应用开始时的设置指令，进行了声音设置界面的开启操作。

S70310、响应于用户对合成控件(如悬浮窗)显示开关的开关指令，对应设置合成控件是否在显示屏上显示。
需要说明的是，S7031-S70310并没有先后顺序的要求，用户可以同时设置几个参数。
具体的，一种可能的实现方式可以参考图8。
图8为本公开实施例提供的一种声音设置界面示意图。如图8所示，用户在声音设置界面上，通过扬声器选择控件，用户可以选择用“有线耳机”或者是直播一体设备自带的扬声器，即“本机扬声器”；通过麦克风选择控件，用户可以选择“有线耳麦”、“本机麦克风”、“卡农麦克风”；通过耳返开关控件，用户通过向右/向左拨动开关控件，开启或关闭耳返效果，并且在耳返开关控件上，还包括提示文本，如“本机扬声器不支持耳返功能”，提示用户耳返功能与扬声器选择直接是具备关联设置的，以避免用户参数选择不当，影响使用效果；同理，闪避开关控件和悬浮窗开关控件也具备类似的操作，具体内容参见图8。
图8中的美声选项即为音效美化效果的选择控件，通过单击右侧展开图标“>”，即可展开音效列表，供用户选择对应的音效美化效果，在本公开的各个实施例中，音效美化效果包括：原声、KTV、磁性、老唱片、空灵、剧场等音效特性，每种音效对应着多个音效设置参数，通过选择特定音效，可以快速设置各个参数，降低了音效设置的专业门槛，使得不具备专业技术的主播也可以进行简单方便的音效设置。
图8的最下方为悬浮窗即合成控件的快捷键选择阵列，用户只需要选中各个按钮控件，则设置显示对应的待合成音频的快捷键，便于用户在直播开始后，在直播界面中通过快捷键直接进行音频合成。
本公开实施例提供的音频合成方法，在图2、图3和图5所示实施例的基础上，通过在没有开启摄像头或者直播开启之前，获取用户的声音设置操作，然后响应于用户的声音设置操作，在显示屏上显示声音设置界面，再根据用户对声音设置界面上各个参数控件的设置指令，对应设置各项音频控制参数，解决了主播无法简便快捷地更改各项声音相关的设置参数，需要专业技术人员辅助的技术问题。使得声音设置和合成控件的快捷键设置简单方便，提高了用户对于直播一体式终端的使用体验感。
在一种可能的设计中，在本公开的各个实施例的基础上，直播一体机即直播一体化设备通过外接接口连接至少一个快捷键键盘，步骤S202：接收用户对合成控件的音频合成操作，包括；
接收快捷键键盘发送的操作指令，操作指令是快捷键键盘响应于用户的操作而确定的；
根据操作指令确定对应的待合成音频。
值得说明的是，外接接口包括：无线接口以及有线接口。
图9为本公开实施例提供的一种直播一体化设备外接快捷键键盘的场景示意图。如图9所示，直播一体机91通过有线接口或无线接口连接快捷键键盘92，用于实现本公开各个实施例的音频合成方法的合成控件911中的多个子控件与键盘上的按键呈一一对应关系。
在一种可能的设计中，快捷键键盘上各个按键与显示屏上各个子控件的对应关系是可以任意设置的。快捷键键盘包括：机械按钮式键盘、触控屏等。用户点击快捷键相当于在显示屏上点击了对应的子控件，同时，子控件切换显示为被选中的状态。
还需要说明的是，子控件在被点击选中后，可以用条形进度条或扇形进度图的形式，同步显示待合成音频的播放进度。
图10a-10c为本公开实施例提供的一种合成控件在待合成音频播放时显示播放进度的示意图。如图10a所示，在用户点击了“笑声1”子控件后，在子控件上显示播放“笑声1”所对应的音频的播放进度条。
如图10b所示，在用户点击了“笑声1”子控件后，子控件的背景颜色或背景图案以旋转渐变的形式来显示“笑声1”所对应的音频的播放进度条。
如图10c所示，在用户点击了“笑声1”子控件后，子控件的背景颜色或背景图案以从左至右、从右至左、从上至下、从下至上、从左下至右上、从右下至左上等方式中的任意一种渐变的形式来显示“笑声1”所对应的音频的播放进度条。
这样主播就能够知道待合成音频的播放进度，进一步的，可以通过再次点击子控件结束播放，或者是点击其它子控件混合播放多个待合成音频，增加了直播音频合成的操作灵活性，提升直播时的现场音频效果，提高用户体验。
